The Prince Charlie coatee is the least formal of all the Highland eveningwear jackets, hence it being the equivalent of the dinner-jacket or Tuxedo.
Please don't be so quick to carve bold statements in stone such as "The black Argyll jacket is not the equivalent of a tuxedo."

One of my favourite "go-to" sources on Highland dress is MacKinnon of Dunakin's small book Tartans and Highland Dress. On page 78, Dunakin wrote:

"Yet another effective style is to have an ordinary day-pattern jacket and vest, with Highland cuffs, pocket flaps and shoulder straps, made up in black vicuna with silver buttons. This can be worn with a lace jabot or a bow tie, and it preserves the flow and dignity of the (Highland) dress. This has always been a popular style with youths but was not so often worn by adults till recently.
... One of the most attractive aspects of the dress is the very wide choice of styles,all equally "correct", although their desirability depends much on the eye of the beholder. The only thing that can be said about evening dress doublets and coatees is that ( except for men dancers in competitions ) they should not be worn as day wear."

There is ample evidence to show that what we call an "Argyll" jacket is perfectly at home as part of evening dress.
